argparse-type-helper 0.1.0

an easy-to-integrate typed argument parser

Argparse Type Helper

A lightweight helper that lets you leverage type hints with argparse.

Features

• Class-based schema Bundle all your arguments in a single @targs-decorated class.
• Identical API Each field uses the same parameters as argparse.add_argument (help, action, nargs, etc.).
• Automatic registration One call to register_targs(parser, YourArgs) wires up all arguments on your ArgumentParser.
• Typed extraction After parse_args(), call extract_targs() to get a fully-typed instance of your class.
• Hybrid usage Mix native parser.add_argument(...) calls with class-based definitions in the same parser.
• Docstring support Use docstrings to automatically generate help text for your arguments.

Installation

pip install argparse-type-helper

Usage

See example.py.

Why not typed-argparse?

typed-argparse is a great library, but it replaces the familiar argparse.add_argument API with its own argument-definition interface, which can be a hurdle when integrating into an existing codebase.

argparse-type-helper, by contrast, is a simple helper that allows you to use type hints with argparse with minimal learning curve. It uses the same argparse API you’re already familiar with, and you can even mix native argparse usage with class-based definitions in the same parser.
